MACHINE FOR BARBING FENCE-WIRE.

SPECIFICATION: forming part of Letters Patent No. 237,129, datedFebruary 1, 1881.

Application filed September 25, 1880.

I To all whom it may concern Be it known that I, WILLIAM A. Roocr, ofNew York, in the county and State of New York, have invented a ncw andImproved Machine for Winding Barbed Fence -Wire, of which the followingis a specification.

Figure 1 is a' plan or top view of my improved machine; Fig. 2, a sideview of the same. Fig. 3 is a vertical cross-section of the same takenon the line 0 c, Fig. 2. Fig. 4 is a detailed top view of the twowinding-shafts, on a somewhat enlarged scale; Fig. 5, a detailed sideview of the same; Fig. 6, a side view, partly in section, on the line 0k, Fig. 4. Fig. 7 is a cross-section on the line We, Fig. 4. Figs. 8, 9,10, and 11 are detailed sectional views of the wires in their successivestages of formation.

This invention rel-atesto a new machine for applying the barbs to thedouble strands of fence-wire; and it consists in the combination, witheach other, of two peculiarly-actuated winding-shafts thatembracethe'strands, and with mechanism for feeding the strands, for cutting thebarbs, and for compressing, finally, and in a perfect form, the coiledportions of the barbs.

The machine isintended to produce an improved barb, which is describedin an application for apatent filed by me on the 21st day of June, 1880,which barb, briefly described, consists, when completed, of twoprojecting prongs and of an inner looped portion, all placed in the samehorizontal plane on top of the strands, as is more clearly indicated inFigs. 1 and 11.

The invention also consists in a new process of coiling the barb byfirst winding one loop, then part of the next loop, then detaching thebarb from the coil or feed-wire,and, finally, compressing it in such away as to complete 'mation, alias hereinafter described.

In the accompanying drawings the letter A represents the frame-work ofthe machine, which frame-work carries a suitable drivingshaft, B, thatimparts motion, by gearing or otherwise, to shafts (J and D. The shaftD, which is clearly shown in Fig. 1, transmits motion, by gearin gs a. bor otherwise, to the shaft E; but the gear-Wheel a has part of its edge(No model.)

left smooth, so that it will not rotate the wheel 12 and shaft Econtinuously, but intermittently.

The shaft E, by a gear-wheel, d, revolves a vertical shaft, F, (seeFigs. 4, 5, and 7,) which carriesatoothed disk, e, that gearsalternately into pinions which mesh into beveled pinions f g. The pinionf is smaller than the pinion g, and' the toothed portion of the disk 0is of such extent that it will first revolve the pinion f one entirerevolution, and afterward revolve the pinion 9 about two-thirds of arevolution. Another partly-toothed disk, h, gears into a pinion thatmeshes into pinion g, as shown in Fig. 7, and has for its object tobring said pinion g hack to its normal position at or before the timethe disk 0 turns the pinion f. The pinionfis fitted upon one of theWinding-shafts, G, and the pinion g upon the other windingshaft, H. Boththese winding-shafts are tuhular, and through them are passedlengthwise, and gradually fed forward, the strands I I of thefence-wire, and around portions of the said strands the two saidwinding-shafts are turned, each in its proper ratio, as hereinafterdescribed.

The shaft G is hung and revolves in suitable bearings that project fromthe frame A; but the shaft H is hung in a swiveled frame, J, (see Fig.6,) in bearings t, that are pivoted horizontally in frame J, so that onsaid pivots the shaft H may vibrate vertically, and the frame J,moreover, is, by a vertical pivot, j, pivoted to the frame A, to becapable of horizontal vibration on its said vertical pivot.

A spring, k, Fig. 6, placed into the frame J under the shaft H, holdsthe latter normally at a higher plane than the shaft G, as indicated inFig. 5; but a lever, l, which is actuated by a rod, m, that joins thecompressionlever L, serves, at the proper moment, to depress the shaft Hlevel with the shaft Gr. Thus by the joints on which the shaft H iscapable of moving I am able to have it normally in the position shown inFig. 8; but to depress it, when desired, into level with the shaft G, asshown in Fig. 9, and to swing it while so on level with the shaft Gnearer to the same, as shown in Fig. 10, and yet meanwhile throughoutall these movements, and even while both said shafts are being revolved,

the strands I I" pass undisturbed through said two winding-shafts. Eachof the windingshafts has at its front end a projecting tooth, as shownat n and 0, Figs. 8, 9, and 10, and also in Fig. 5.

In addition to the movement which can be imparted to the shaft H, thesaid shaft has also a slight reciprocating longitudinal movement, whichis imparted to it in one direction by a spring, 1), and in the oppositedirection by a pin, q, coming into contact with a cam, r, on a collar,8, of said shaft H, so that when the springp is compressed, at the timeq and r are in contact with each other. as shown in Figs. 4 and 6, thefront end of the shaft H will be thrown behind the line of the front endof the shaft G; but when the cam rhas no longer contact with the pin qthe two ends of the said two shafts G and H will be in line with eachother. A suitable crank, z, or eccentric on the shaft C serves, by arod, 1 or otherwise. to impart lateral motion to the shaft H,carryingit, at proper intervals, nearer to or farther away from theshaft G. The lever L, which has already been mentioned as moving thelever l, is pivoted at u,and derives its vibratory movement from a cam,r, on shaft E, and has atits lower front end a compressing-block, 1r,for finally shaping the barb, and the lever L acts so that at the timethe block to is brought down on the barb the rod m is raised and 1e ver1 moved, and the shaft H depressed to be level with the shaft G; but atthe time the block w is elevated the spring k is thereby liberated toraise the shaft H to its former plane.

Now, assuming that the strands I I had been drawn through the hollowshafts G H and properlystretched and sufiicientl y fed forward, the barbis applied by placing the undetached end portion of the barb-wire M overthe strand I that passes through the shaft G, and under the strand 1"that passes through the shaft H, as shown in Fig.8; for in itsnormalposition the shaft H is at a higher plane, and holds its strand Iata higher plane, than the shaft G, and in said normal position bothteeth at and 0 are verticallyabove said strands, as clearly shown inFig. 8. It will be remembered that when the barb is thus placed, asshown in Fig. 8, it is beneath the tooth 0, whereas the tooth n is drawnback; and also that when the parts are in this position one end, 1,ofthe barb-wire is cut off to form the prong, but the other end is not yetdetached. Now, the first thing to do is to revolve the shaft G oncearound its axis. This will cause its tooth o to lap the pron ged end 1of the wire M around the strand I that passes through the shaft G, andto place the extreme pronged end 1 upon or on top of the other strand,1", that passes through the shaft H, so that now the position shown inFig.9 is attained, in which position one loop of the barb-wire isalready formed around the strand I that passes through the shaft G. Theshaft G has a slight rectilinear motion, permitted by a suitable spring,x, which enables the spiral loop formed on wire M to bring the twostraight parts of the barb-wire out of the same vertical plane, and tocrowd shaft G back in coiling, and in this position thepronged end 1 ofthe barb is on top of the strand I", whereas originally it was below thesame. The shaft H now begins to turn and the shaft G remains stationary.Upon beginning to turn the shaft H is first liberated from the effect ofthe pin q and cam r, and its tooth pushed forward over the wire M. Atthe same time, by the action of the eccentric t, the shaft H is movednearer to the shaft G, and now as it makes two-thirds of a revolution,or thereabout, in direction of arrow shown in Fig. 9, it coils thepronged end of the wire partly around the strand 1", bringing the partsinto the position shown in Fig. 10, which figure shows the position ofthe tooth a after it has completed its two-thirds revolution. The toothn, with shaft H, is now again turned back by the action of the toothedwheel h, and thereby relieved from contact with the wire M, and thebarb-wire is now detached by suitable shearing mechanism N, that isactuated by a cam-lever, 0, from the body or main coil of said wire. Thefeed mechanism of the strands I I" is next set in motion, and thestrands carrying the partlyfinished barb are moved ahead until thepartlyfinished barb arrives under the block 10 and between twocompression-jaws, y y, and overa fixed anvil, l. The compression jaws,by suitable eccentrics a on the shafts C and D, are now moved towardeach other against the coiled parts of the barb-wire, and then the blockto is brought down, so that between said jaws, and between the block toand the anvil P, the partly-finished coil is compressed laterally, so asthereby to roll that end portion 1 of the wire M which remains betweenand above the two strands I I", as in Fig. 10, more completely aroundthe strand I until the original prong 1 is horizontally on a plane withthe newly-formed prong 2, produced by the shears, and the finished barbassumes the shape shown in Figs. 1 and 11. The barb-wire is now, fromits coil, fed again into the machine by suitable gripin g apparatus R,actuated by suitable earn 1), to bring another portion of it in frontthe ends of the shafts G and H, in the manner shown in Fig. 8, and theabove-mentioned operation is again continued, and so forth, adinfint'tum.

It will, of course, be understood that whenever the shaft G begins arotation the tooth n of shaft H is withdrawn from above the barbed wire,so that the return motion imparted to the shaft H by the upper disk, h,which is necessary in order to bring tooth n from its lower position(shown in Fig. 10) back into the upper position, (shown in Fig. 9,) maybe effected without disturbing the action of the shaft G.

I claim- 1. In a machine for barbing fence-wires, the combination of thehollow winding-shaft G with the hollow winding-shaft H, which shaftstrands, and then partly around the other, and
